As shown in FIGS. 9 to 12 , the light-transmitting plate 3 is provided with a lens structure. The light-transmitting plate 3 includes a lens frame 18 and a plurality of lenses 19 provided on the lens frame 18. The plurality of lenses 19 are arranged corresponding to the light-emitting elements 6 and protrude in a direction away from the light-emitting elements 6. The lens frame 18 is provided with a plurality of through holes 20 corresponding to the plurality of lenses 19.

The plurality of lenses 19 are uniformly arranged in a plurality of sectors on the lens frame 18 around an axis of the lens frame 18 In each sector, a plurality of rows of the lenses 19 are provided. In each row of lenses 19, a plurality of lenses 19 are arranged in an arc. In the same sector, there is a fourth gap 21 between two adjacent rows of lenses 19. There is a fifth gap 22 between two lenses 19 between two adjacent sectors. A circle formed by the lenses 19 closest to the axis of the lens frame 18 has a minimum radius, and as the lenses are located away from the axis of the lens frame 18, a radius of a circle formed by the corresponding lenses increases gradually.

The lens 19 includes a first lens portion 29, the second lens portion 30, the third lens portion 31, and the fourth lens portion 32 that protrude from a side thereof away from the light-emitting elements 6 and are provided corresponding to the first lamp bead 11, the second lamp bead 12, the third lamp bead 13, and the fourth lamp bead 14, respectively.

The second lens portion 30 and the fourth lens portion 32 are respectively provided with a groove 23 on a side away from the second lamp bead 12 and the fourth lamp bead 14. Certainly, the grooves 23 can be provided on the first lens portion 29 and the third lens portion 31 on a side away from the first lamp bead 11 and the third lamp bead 13. The arrangement of the grooves 23 can increase the light emission angles of the lamp bead 11, the second lamp bead 12, the third lamp bead 13, and the fourth lamp bead 14.

As shown in FIG. 13 , the first lens portion 29, the second lens portion 30, the third lens portion 31, and the fourth lens portion 32 of the lens 19 are server as a plurality of convex lenses. The light emitted from the light-emitting element 6 passes through a light-incident surface of the lens 19, and is condensed by the plurality of convex lenses and then is directed to the outside. Since the focal length of the convex lens will affect a light output angle of the light passing through the convex lens, the above arrangement can enable the LED lamp to have different light output angles. In an embodiment, the first lens portion 29 and the third lens portion 31 have the same focal length, the second lens portion 30 and the fourth lens portion 32 have the same focal length, and the focal length of the first lens portion 29 or the third lens portion 31 is different from the focal length of the second lens portion 30 or the fourth lens portion 32. The entire surfaces of the first lens portion 29 and the third lens portion 31 away from the light emitting element 6 are convex surfaces, and the first lens portion 29 and the third lens portion 31 refracts light at an angle of 60°, that is, the light output angle of the light passing through the first lens portion 29 or the third lens portion 31 is 60°. The grooves 23 are provided on the second lens portion 30 and the fourth lens portion 32, and second lens portion 30 and the fourth lens portion 32 refracts light at an angle of 110°. In this way, when the light emitted from the second lamp bead 12 and the fourth lamp bead 14 passes through the light-entering surface of the lens 19, and then is condensed by the second lens portion 30 and the fourth lens portion 32 and then directed to the outside at the light output angle of 60°. Since the grooves 23 are provided, when the light emitted from the first lamp bead 11 and the third lamp bead 13 passes through the light incident surface of the lens 19, the light is condensed by the second lens portion 30 and the fourth lens portion 32 and then directed to the outside at the light output angle of 110°. That is, the focal length of the second lens portion 30 and the fourth lens portion 32 is greater than that of the first lens portion 29 and the third lens portion 31, and the light output angle of the light passing through the second lens portion 30 and the fourth lens portion 32 is greater than that of the first lens portion 29 and the third lens portion 31.
